You're right, and at first I thought 'it's not so bad, it's just making fun of Biden'. As I read through the pages of this thread, I realised that my experiences as an Irish woman living outside of Ireland, have skewed my perception of what is appropriate. I've lived in several countries outside of Ireland, but the anti Irish microagressions happened exclusively in England, and it was often so upfront and 'normal'.
-Mocking my accent when I spoke; literally parrotting back what I said. This happened all.the.time. and was the thing I hated the most.
-The never ending, boring statements that no Irish people ever say, eg 'Top o' the mornin' to ya'/'potatooooes'/turty tree and a turd
-asking if I was in/supported the IRA/did I have a gun
-jokes about me and my husband leaving bombs in bins
- references to leprechauns and pots of gold when I made a comment during a staff meeting
Then there were phrases that were part of the language such as 'having a paddy' and 'don't be so Irish (meaning stupid).
These are off the top of my head but it was constant, on a loop, never ending and very, very boring.
I got so used to it that it was just a normal part of my life. I got so used to just shrugging my shoulders at it that I am pretty sure I internalised it a bit. Nobody else seemed to think it was offensive so I just took it on the chin and let it go, thinking I was being over sensitive. I definitely felt 'othered' quite a lot.
